Cheryl Cole demonstrates off strange Minnie Mouse hairstyle on The X Factor: Over the past few weeks of The X Factor live shows, Cheryl Cole and Dannii Minogue have been competing to be the best dressed. But on last night's results show, their outfits barely got a look in thanks to Cheryl's bizarre hairstyle.

The 27-year-old wore her long red hair tied up in a bow on her head with the loops looking like ears - drawing comparisons with cartoon character Minnie Mouse.

Racy: Cheryl teamed her bizarre hairstyle with a very revealing Editions by Georges Chakra 2010 gown and towering Brian Atwood platform sandals But while her hair may have looked more suitable for children's hour, her outfit was anything but.

After flaunting her cleavage in a low-cut gold Roberto Cavalli dress on Saturday, she managed to outdo herself last night by showing plenty of flesh in her revealing Editions by Georges Chakra gown. The flowing chiffon skirt was slashed to the thigh showing plenty of leg, while the keyhole top barely covered her decolletage.

Rock n rolll: Dannii Minogue wore a pale blue leopard-print Emilia Wickstead jersey dress and Christian Louboutin pumps, which she teamed with a quiff Meanwhile, Dannii went for more rockier look in a pale blue and black leopard-print Emilia Wickstead dress and Christian Louboutin heels. Although in normal circumstances, Dannii's quiff would be considered quite edgy, it looked rather tame in comparison to Cheryl's wacky 'do.
